Ultrasky Technical Data

Choosing the right high performance roof glass for your lantern is the most important element to ensuring that the thermal performance has been optimised to make it suitable for extensions in domestic properties. Typical U value with 1.0 glass for a 1000mm wide x 2000mm long rooflight is 1.4 W/m2K.


Our Standard glass choices included into your price are:

  • Ambi-Blue self-cleaning
  • Ambi-Neutral self-cleaning


Both of these glass options have a coating that reflects UV rays in sunlight to generate a photocatalytic process that loosens and breaks down organic dirt particles on the surface of the glass. The surface of the coating is hydrophilic. Therefore instead of forming droplets, it attracts water so that it spreads and forms a thin film that “sheets” away quickly, and dries off without leaving unsightly “drying spots”.


Self-cleaning glass

Self-cleaning glass leaves less dirt and grime adhering to the glass resulting in the glass staying cleaner for longer, meaning less maintenance is needed.

See our download area for full glass specification.

Other glass options are available; prices for these are available upon request.
